A witness in the trial of accused Nazi guard John Demjanjuk is himself under investigation for Nazi killings, a German prosecutor tells the AP. Former guards have stated that 94-year-old Alex Nagorny participated in mass shootings at the Treblinka concentration camp in occupied Poland, says the prosecutor. Nagorny, a Ukrainian, was a Red Army soldier captured by the Germans, as prosecutors say Demjanjuk was.

Nagorny admits he trained at the Trawniki SS camp and has testified that he served as a guard at the Flossenbuerg concentration camp in Bavaria with Demjanjuk, who he lived with after the war. But he says he never served at Treblinka. Demjanjuk, meanwhile, holds that he didn’t serve the Nazis at all. Nagorny wasn’t able to identify Demjanjuk as the 90-year-old lay on a bed in the courtroom, saying the man on the bed bore "no resemblance" to the Demjanjuk he knew.
